REDUCED GENERATION OF AMMONIA IN NICKEL CATALYST OF REFORMER

REDUCED GENERATION OF AMMONIA IN NICKEL CATALYST OF REFORMER

Reformation of natural gas without excessive production of ammonia, even if the natural gas includes as much as 14% nitrogen, is achieved in reformers including tubes (75) having outer chambers (78) with catalysts therein, a first stage (80) of catalyst having between about 10% and about 25% nickel,...

Zusammenfassung:Reformation of natural gas without excessive production of ammonia, even if the natural gas includes as much as 14% nitrogen, is achieved in reformers including tubes (75) having outer chambers (78) with catalysts therein, a first stage (80) of catalyst having between about 10% and about 25% nickel, a second stage (81) of catalyst having less than 10% nickel, and a final stage (82) having 2% or less rhodium catalyst of a low concentration.
